Auto merge of #18205 - noahmbright:object_safety, r=HKalbasi

Rename object_safety

First PR here (yay!), so I read some of the getting started docs. There are a couple references to `handlers.rs`, which as far as I can tell has been refactored into `handlers/*.rs`. I made some tweaks to that in one commit. There is one fixme about a function called `to_lsp_runnable`, which I can't find anywhere at all. I can update that if I get some more info there.

Otherwise I changed references to object safety, is object safe, etc., trying to match case/style as I went. There was one case I found where there's a trait from somewhere else called `is_object_safe`, which I found defined in my cargo registry. I didn't touch that for now, just marked it with a fixme
